SG2001/A
GENERAL DESCRIPTION
FEATURES
- Low Output Noise: 30µVRMS typ(10Hz to 100KHz)
- Ultra-Low Dropout Voltage:
The SG2001/A series low-power, low-noise, low-dropout,
CMOS linear voltage regulators operate from a 2.5V to 5.5V
input and deliver up to 150mA. They are the perfect choice
for low voltage, low power applications. An ultra low
ground current (100µA at 150mA output) makes these
parts attractive for battery operated power systems. The
SG2001/A series also offer ultra low dropout voltage
(105mV at 150mA output) to prolong battery life in
portable electronics. Systems requiring a quiet voltage
source, such as RF applications, will benefit from the
SG2001/A series’ ultra low output noise (30µVRMS). An
external noise bypass capacitor connected to the device’s
BP pin can further reduce the noise level.
105mV at 150mA output
- Low 77µA No-Load Supply Current
- Low 100µA Operating Supply Current
at 150mA Output
- Thermal-Overload Protection
- Output Current Limit
- Preset Output Voltages (±1.6% Accuracy)
- 10nA Logic-Controlled Shutdown
- Available in Multiple Output Voltage Versions
Fixed Outputs of 1.2V, 1.5V, 1.8V, 2.5V, 2.8V,
2.85V, 3.0V, 3.3V, 3.6V, and 5.0V
Adjustable Output from 1.5V to 5.0V
The output voltage is preset to voltages in the range of 1.2V
to 5.0V. Other features include a 10nA logic-controlled
shutdown mode, foldback current limit and thermal shut-
down protection.
Devices come in 5-pin SOT23 package.

Application Notes
When LDO is used in handheld products, Attention must be paid to voltage spike which would damage
SG2001. In such applications, voltage spike will be generated at changer interface and VBUS pin of USB
interface when changer adapters and USB equipments are hot-inserted. Besides this, handheld products will
be tested on the production line on the condition of no battery. Test Engineer will apply power from the
connector pin which connects with positive pole of the battery. When external power supply is turned on
suddenly, the voltage spike will be generated at the battery connector. The voltage spike will be very high, it
always exceeds the absolute maximum input voltage (6.0V) of LDO. In order to get robust design. Design
Engineer needs to clear up this voltage spike. Zener diode is a cheap and effective solution to eliminate such
voltage spike. For example, BZM55B5V6 is a 5.6V small package Zener diode which can be used to
remove voltage spike in cell phone design. The schematic is shown in below:
